DUMPING MECHANISM FOR WAGONS.

SPECIFICATION forming part of Letters Patent No. 726,651, dated April21, 1903.

Application filed December 10, 1902. Serial No. 134,628. (No model.)

To all whom, it may concern:

Be it known that I, JOSEPH GRUNDLER, a citizen of the United States, anda resident of Jersey City, county of Hudson, and State of New Jersey,have invented certain new and useful Improvementsin Dumping Mechanismfor Wagons, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof, in whichsimilar letters of reference indicate corresponding parts.

This invention relates to improvements in dumping mechanism for wagons.

The invention has for its object to produce an easy-working,inexpensive, simple, and effective mechanism whereby a wagon may bequickly dumped by'a single operator.

The invention has also for its object the production of a system oflinkwork which, operating witha revoluble shaft and proper connections,will bygiving the joperatorthe advantage of leverageenable himquicklyand easily to lift the. front end of a wagonbed for dumping the same. II

The invention also hasfor its object divers other novel featureshereinafter ,more'fully set forth. r v q I The invention consistsin thecombination and arrangement of divers levers attached to the bed andrunning-gears of a wagon and operating in connection with a revolnbleshaft,

and a chain connecting said shaft andsaid system of levers, so as toenable an operator ble shaft and said system: of levers, so thatv byturning said revoluble shaft the operator can readily raise saidwagon-bed into a position to be easily dumped.

The invention also consists in divers other novel features, which willbe fully understood from the following general description and theannexed drawings and will be subsequently pointed out in the claims.

.therunning-gears, and C the wheels.

In the accompanying drawings, which are hereby made a part of thisspecification, Figure 1 is a vertical sectional view of a wagonembodying my invention, taken on the line at w of Fig. 2. Fig. 2 is asectional plan view of the same, taken on the line 1 y of Fig. 1. Fig. 3is a side view in elevation of a wagon embodying my invention with thebed in proper position for dumping and with a part broken away to betterdisplay the mechanism.

In the accompanying drawings, A designates the bed of a wagon, B theside rails of To the bottom of the bed is attached a bracket a. Thisbracket consists of two horizontal ears joined together by'a bottomplate integral with them and standing'at right angles to them. In thisbracket is journaled the shaft a. Upon this shaft are pivotally mountedby one end of each the double links D and D. Theselinks consist each oft-wopieces, (designated, respectively, as bb and b 12 which areshort'strips of flat metal of equal length and formed with registeringeyes at each end.

These links are mounted on shaft a outside of the bracket a and a littleapart, so as to accommodate other parts of the mechanism.

Upon across-bar of the running-gears is fastened the bracket a similarin its construction to the bracket a. I

a a designatetwo levers. These are pivoted by one end at a to thebracket a and mounted pivotallybythe other endon the shaft a, eachbetween two parts of the links D and D. This is the upper end of the twolinks.

0 c 'd'esignate two bent levers pivoted by one end to the lower ends ofthe links D and D by the shaft 0 passing through their ends and throughthe lower ends of the links. The arrangement is such that one end ofeach lever comes between the two parts of one of the links.

0 designates" a rod which passes through theonter ends ofthe levers c cand extending outside of them, as illustrated in Fig. 2, slides in thenotches t and z", formed in the side rails B B. These notches are cut inthe upper inside corners of the side rails. Their sides and ends areplane perpendicular surfaces. The bottoms are formed with planehorizontal surfaces at and 4"; but at r this surface is concave, asillustrated. In these notches move the ends of the rod 0.

d designates hearings in the running-gears, in which is journaled theshaft 01, turned by the crank d Between this shaft (1 and the rod 0extend the chains e, which are arranged to wind on said shaft and drawthe rod 0 in the notchest' t" toward the said shaft (1. If it bedesired, the shaft d may be equipped with a ratchet-wheel and pawl tocontrol its backward motion.

01 and n are guide-plates which are fastened to the bottom of the bed Anear its rear end and bearing on the inside surfaces of the side rails BB prevent lateral displacement of the rear end of the bed.

0 and 0 are straps of metal connecting the rear ends of the bed and therunning-gears to prevent the bed from slipping too far rearward when itis raised to be dumped. These straps, however, are not necessary to thesuccessful operation of the device and may in some cases be omitted, ifit be found desirable.

In the operation of my invention at first the bed which has beenpreviously filled is in the position illustrated in Fig. 1, lyinghorizontally on the running-gears. Then the .rod 0 will be resting onthe horizontal surfaces 1' of the notches i 'i'. When the operatorbegins to turn the shaft d by means of the crank d and wind the chains 6upon the shaft, at first the rod 0, bearing in the notches i i, will actas a fulcrum as the chains begin to raise the links D D. As long as itacts as a fulcrum it will remain on the horizontal surface; but when thechains have lifted the links a little the motion of the levers ct willdraw the rod off the horizontal surface onto the concave surface. Thenuntil the bottom of the concave surface is reached by the rod theconcavity will assist the operator in raising the bed. When the bottomof the concavity has been reached by the rod, the parts will be in sucha position as to give the operator full advantage of the leverage, sothat he can easily raise the bed to its full height, drawing up the rodonto the horizontal surface 1". The rod will not be apt to slip on thissurface, and so the bed will be held steadily in position for dumping bythe joint action of the levers and the rod 0 and the chains 6. When thebed is empty and the chains released, a slightjarwill cause the bed tosink down into its horizontal position on the running-gears and restorethe mechanism to its normal position. In the meantime the guideplates atand n prevent lateral displacement of the rear end of the bed, and thestripso 0 limit the rearward slip of the bed; butif for any reason alonger slip endwise than these strips 0 0' will allow should be desiredthey may be removed and then the bed will slip rearward as far as thesaid lifting mechanism will allow and will whenlowered be returned toits normal position on the running-gears by the action of the saidlifting mechanism.

Aside from what is herein disclosed a wagon to which my device isapplied is used in the common and well-known way. I do not, however,limit myself strictly to the construction and arrangement herein setforth, as it is obvious that under the spirit and scope of my inventionI am entitled to slight variations of construction and arrangement.

Having now described what myinvention is, how itis constructed, andhowit is used, what I claim as my invention, and desire to secure byLetters Patent, is
